Liquid Fertilizer Setup
Liquid fertilizer distribution systems
a
are optional on the
YP24 and are optimized for use with the Great Plains
PFC2000 tank.
The dry fertilizer system of the YP2425F is covered in a
separate manual, 403-362M.
If installed, there are several points of fertilizer setup
and/or adjustment:
1. Pump setting dial or sprockets
Basic pumping rate is adjusted at pumps.
For the cart-mounted pump and newer wing
ground-drive pumps, a dial on the pump sets rate.
For prior wing ground-drive pumps, sprocket
selection sets rate.
Refer to the Seed Rate manual and the tank cart
Operator’s manual.
2. Row orifice setup
Orifice plate sizes are chosen to assure consistent
pressure at all nozzles. Refer to the Seed Rate
manual.
3. Relief valve setting
See “Fertilizer Relief Valve” on page 61.
4. Inlets
Both Type 2 (2-section, single inlet) and Type 3
(3-section, 3-inlet) systems have quick-connect inlets
and shutoff valves at the back of the planter. See
page 20 for hook-up details.
5. Strainer setup
The optional ground drive pumps include a strainer.
The mesh screen size must be compatible with the
orifice plates in the distribution system. Refer to the
Seed Rate manual.
Great Plains recommends checking with your local
agronomist as soil conditions vary. Soil conditions in your
area may need less or more fertilizer than represented in
these charts. In furrow, do not exceed 12 gallons per
acre in any case.
The liquid fertilizer system is designed to operate
(ideally) between 15 and 40 psi, but in no case more
than 65 psi. Several system elements affect system
pressure, and need initial setup, periodic maintenance,
and adjustment when changing seed rates.
a. Type 2, Type 3, or both, with or without planter-mounted ground drive pumps for Type 2. See page 21 for details.
